Columbus is served by 4 active area codes as of 2026, layered through decades of overlays and splits across the metro area. This guide walks through which code covers which part of the region, why so many codes are needed, and what new codes may come next.
The Short Answer
Columbus currently has 4 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
Columbus has roughly 2,225,377 residents as of the most recent estimates. That population, combined with the spread of mobile and VoIP lines per household, determines how often new area codes are needed.

How Columbus’s Area Codes Grew Over Time
Columbus received its first area code, 614, when the North American Numbering Plan launched in 1947. That single code initially covered the entire state, and subsequent splits and overlays narrowed it over the decades that followed.

- 1997 — 740 split off from 614 on November 8, 1997, taking the rural southern and southeastern portion of the old 614 territory and leaving 614 to cover Columbus and Franklin County.
- 2015 — 220 activated as an overlay of 740 effective April 22, 2015, covering the same central and southeastern Ohio territory and bringing 10-digit dialing to that region.
- 2016 — 380 activated as an overlay of 614 on February 27, 2016, sharing the Columbus and Franklin County territory; 10-digit local dialing took effect there on January 30, 2016.
Columbus Area Codes by District
Columbus and Franklin County (614, 380): Columbus proper and the inner suburbs in Franklin County, with portions spilling into Delaware, Fairfield, and Union counties. 614 is the original 1947 code; 380 was added as an overlay in 2016.
Outer metro and central/southeastern Ohio (740, 220): The outer Columbus metro counties, including Newark, Lancaster, Delaware, Circleville, and Marion, along with the wider southeastern Ohio region. 740 split off from 614 in 1997; 220 was added as an overlay in 2015.
What’s Next for Columbus Area Codes
The Columbus area’s core 614/380 pair and the surrounding 740/220 pair both gained overlay relief in the 2015-2016 window, which extended their numbering runways considerably. NANPA’s most recent NPA exhaust projections show neither 614/380 nor 740/220 on the near-term relief schedule, though continued rapid population growth in central Ohio means the 614/380 pool serving Franklin County is the more likely candidate for future pressure as the decade progresses.
Frequently Asked Questions
How many area codes does Columbus have right now?
Columbus has 4 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Columbus?
614 is the oldest active area code in Columbus, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Columbus?
The most recent area code addition to Columbus was 380, activated in 2016. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Columbus need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
How many area codes does Columbus have?
The Columbus metro is served by four area codes. Columbus proper and Franklin County use 614 and its overlay 380, while the outer metro counties such as Licking (Newark), Fairfield (Lancaster), and Pickaway (Circleville) use 740 and its overlay 220.
What is the original Columbus area code?
614 is the original Columbus area code, assigned in 1947 as one of Ohio’s four founding area codes. It has become closely identified with the city itself and appears on local apparel and branding as shorthand for Columbus.
What is the 380 area code?
380 is an overlay of 614, introduced in 2016 to add numbering capacity for Columbus and Franklin County. It covers the same geographic area as 614, so a 380 number is a Columbus number; new phone lines in the city may be assigned either code.
Do I need to dial the area code for local calls in Columbus?
Yes. Because Columbus uses overlay codes, 10-digit dialing is required for all local calls. In the 614/380 area this took effect on January 30, 2016, and the surrounding 740/220 area requires 10-digit dialing as well.
